Doors made of uPVC have been on the market long enough that their strengths and weaknesses are well known.

Unplasticized polyvinyl chloride, usually abbreviated uPVC is a rigid plastic material with many uses. One of those uses is for the construction of doors and window frames. The stock for these products is extruded in formed strips. The strips can then be cut to length, and are heat welded or screwed together at joints.

An obvious advantage of uPVC doors is that they are moisture proof. As such they are excellent for applications in bathrooms and kitchens. As exterior doors they are secure and waterproof. Much less porous than wood, these polyester doors are perfect for locations where hygiene is important such as hospitals and food processing plants or preparation areas. Good disinfection of the plastic is possible, whereas wood can absorb and harbor organic material.

The range of styles is as broad as doors made of any other material. They can be hinged, folding, sliding or operated by roller action. They can open inward or outward. Exterior doors are usually mounted with added security bolts at both top and bottom. PVC doors can be single layer or made from hollow stock. They can accommodate single, double or triple-glazed windows. In short, uPVC is a suitable material for doors of all types and styles.

Designs offered include standard panel doors, french doors, side panels, and transoms in various shapes. There is a broad selection of decorative panels and included window styles. From various manufacturers, there are over 200 styles of uPVC doors.

Cheaply made uPVC doors are more susceptible to sun damage than those of a better quality. Ultra-violet rays will break down the outer surface and cause it to powder. Doors with a film applied to simulate wood grain are more likely to be damaged as the dyes fade. Pay attention to warranties and quality of materials when making purchases.

Large home improvement companies carry rigid vinyl doors, or are able to order them. For those willing to research the manufacturing companies and their various products, it is always possible to order on-line. Talking with a contractor who has experience in installing and maintaining uPVC doors can be helpful.

Since the 1970s, the use of uPVC for doors and windows has been increasing. It has some definite advantages over wood, and in composite with steel or aluminum can be even stronger.
